And there is nothing to try and reinvent the unthinkable sets of keywords. If the words 'abstracts' not in the text of your page, the search engines do not care if you tag keywords stuffed a hundred words 'Abstracts' (this the most popular search term in RuNet). Your page will not be found even in last place search results (not that that would be somewhere in between). Let's try to do is to check (in general, any approval of the creators of the search engines must be checked. They are sly, sometimes powders us brains so we do not know their secrets.) Cite an example. Continue to learn more with: Darius Bikoff. Take the first available site Immigration to America – (he caught me on the second page in the section 'Work' ranking Rambler's Top 100, quite by accident). Let's see the html-code main page of this site (to see the html-code of the page opened in a browser, users should click the right mouse button anywhere on the page and from drop-down menu select 'View Source' – this is for IE6, for other browsers look for such a link, pop-up window text editor and we will see the html-code ready of our page.) Key words, I saw these words, standing next: 'Jokes, karta, Airlines'.
In the visible page text they contain (I checked the service 'search' in the same text editor). So, now let's try to find the home page of our website in four Russian-language search engines (Including Google). In each of our search engine will immediately enter the three words Jokes karta Airlines, to minimize the search results (because each of these words alone, we find a lot of pages, and why waste time in vain, we are interested in searching for a page?).
